A device for ecg derivation from a catheter

Abstract

A device for the ECG derivation from a catheter can be used with a guide wire as well as without a guide wire, and can be manipulated in a simple and sterile manner. The device includes a pipe section exhibiting a channel that includes a contact pin which is connected to a terminal at the outer face of the device and is movable between a first position and a second position, the two positions representing different positions with respect to the channel axis.

1 . A device for ECG derivation from a catheter, comprising a pipe section exhibiting a channel,
 the channel comprising a contact pin which is connected to a terminal at the outer face of the device and is movable between a first position and a second position, the two positions representing different positions with respect to the channel axis,   the channel further comprising a drum being arranged to be rotatable about an axis perpendicular to the channel axis, wherein the contact pin is arranged in an eccentric manner on the drum and, when the drum is rotated about its axis, the contact pin moves along a circular trajectory.

         3 . (canceled) 
     
     
         4 . The device according to  claim 1 , wherein the contact pin crosses the axis of the channel during its transition from the first position to the second position. 
     
     
         5 . The device according to  claim 1 , wherein the first position and the second position are homothetic with respect to the channel axis. 
     
     
         6 . The device according to  claim 1 , wherein at one end of the pipe section, the device exhibits a terminal for a catheter. 
     
     
         7 . The device according to  claim 1 , wherein at one end of the pipe section, the device exhibits a terminal for a syringe.
